Hello there,
RateLimit.GetCurrentCredentialsRateLimits can be invoked 180 times every 15 minutes for a specific user account.
This will give you all the rate limits associated with your current Token.
One of the problem you are facing is that you will have to get the retweets of all the tweets of your contest every x minutes.
What you could do, is use the Lookup query (https://tweetinvi.codeplex.com/discussions/561185).
In a Tweet you have a RetweetCount property that you can use for your contest.
Please let me know if this helps.
